PHP PDO update prepared statement

Question

I'm trying to update my database with the following query:

$sth = "UPDATE rpacks SET rpacks_location VALUES (:location) WHERE rpacks_id = (:id)";
$q = $conn->prepare($sth);
$q->execute(array(':location'=>$location, ':id'=>$id));

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'VALUES ('test') WHERE rpacks_id = ('2')' at line 1' in

Answer 1

There is a mistake in your update query because you used insert query syntax.

Here is the correct query:

$sth = "UPDATE rpacks SET rpacks_location = :location WHERE rpacks_id = :id";

改成：

$sth = "UPDATE rpacks SET rpacks_location = :location WHERE rpacks_id = :id";
